Q- Can we design a MOD-6 counter using the above method? Ans: We firstly draw the state diagram And now we draw the table to represent the desired output of the combinational circuit to reset FFs as: Q2 Q1 Q0 OUTPUT 0 0 0 1 0 0 1 1 0 1 0 1 0 1 […]

USING K-MAPS to design counter
Q- Design MOD-3 ripple counter using (a) Observing outputs (b) K-maps to design the circuit. Ans: (a)We can design the MOD 3 counter using 2 FFs as 3 is less than 4 i.e. 22 and greater than 2. We can see directly that as we have to reset the counter only after 2 i.e. when output is […]
Conversion: D to RS flip-flop
We first write the truth table for required Flip-flop i.e. RS FF Now we write the excitation table of given FF i.e. D flip-flop as Now we combine two tables to get the combinational circuit as: Now we design the combinational circuit to convert J, K to corresponding R, S K-map for D input: And […]
Conversion: RS to JK flip-flop
We first write the truth table for required Flip-flop i.e. JK FF Now we write the excitation table of given FF SR flip-flop as Now we combine two tables to get the combinational circuit as: Now we design the combinational circuit to convert J, K to corresponding R, S K-map for S input: K-map for […]
Conversion: RS to D flip-flop
Let’s first now derive the D flip-flop from RS flip-flop which we have already done: We first write the truth table for required D flip-flop as Now we write the excitation table of given FF SR flip-flop as Now we need to make a arrangement so that we manipulate input D to inputs R, S […]
